It's hard to imagine a herd 96,000 square miles large, that's nearly half the size of France. It's harder still to imagine that enormous herd of majestic, gigantic creatures traveling 600 miles across the great white north every year. Caribou are one of the world's largest migratory animals, and now their journey is accessible to young readers. This volume details their daunting travel in clear, engaging language complemented by easy-to-understand graphics and vibrant full-color photography. A map is also included to give readers a visual sense of the great lengths these hardy creatures endure to complete their truly massive migration.
